It allows device to draw a current as much as using an original adapter. The F75198 support most of the USB Battery Charging Specification worldwide, including BC 1.2, Apple® charging spec (for i-Pad & i-Phones) and specs for Samsung Galaxy Tab. By setting the USB Data pins (D+/D-) to the required voltage levels, then the charging device will recognize the voltage levels, and starts to draw the current to charge. It also equipped with a select pin (SEL) allows users to selection desired charging current for apple devices. The F75198 is suitable for all charger products using USB interface. It provides enhanced ESD protection up to ±8kV on the DP and DM. With the compact SOT23-5 Package, it require minimum external circuits, which can reduce develop & production cost dramatically. 2 Feature List 4.5V~5.5V Single Supply Operation. Automatic USB charger Identification Circuit. Support Apple® Devices fast charging. (Selectable Apple® 1A / 2A mode) Support BC1.2 & YD/T 1591-2009 Charging Spec. Support Samsung Galaxy tab Devices Charging. ±8kV High ESD Protection On DP/DM. Available in SOT23-5 Package. Operate in 0°C to +70°C temperature range 3 Application Field Computer peripherals.

The F75198 is able to identify the types of USB device (Apple devices,BC1.2 USB devices or Samsung Tabs) that is attached to the charging port, and change the configuration of D+/D- data line will emulate dedicated wall adapter instantly. It allows the USB charging port to support both Apple, BC1.2 & Samsung Tab compliant devices. 2 Jan, 2012 Data Sheet F75198 The following Figure explains how the F75198 works: As shown below, F75198 application structure. The F75198 is attached is only controls the D+ / D- signal of the system. It detects the characteristics of the devices attached. Then automatically changes the configuration of D+ / D- according to the type of device which attached to connector. VBUS 5V Power F75198 VBUS Power Figure 6.2 Charger Mode (Auto Detect Mode) Please notice that, the F75198 does not involve any power related operation, it controls only the behavior of the D+ / D- of USB charger port. All the power management & protection mechanism should be finished in the power source block. The F75198 provide only the D+ / D- device recognition. For best result, use the power source should have the capability to provide at least 5V / 2.1A DC power for each USB Charging port. 6.1.2 The Selection of Reference Bias Resistor – SEL The F75198 equipped with 2 sets of reference bias resistors for Apple, one allow for the apple device to draw 2A (max) charging current device (Default) and another allows apple device to draw 1A current only. Users can use a single digital input (SEL) to switch between these two reference bias sets. Table 5.1.2: Truth Table of SEL SEL Description 1 Apple 2A mode 0 Apple 1A mode Although the F75198 has a selection pin, which can change the D+ / D- voltage confirmation towards & ® from Apple 1A, 2A mode. It’s not recommended, However, by use this function as current limit protection, and restrain the charging current of Apple® devices to 1A or less by using this feature. 3 Jan, 2012 Data Sheet F75198 7 Electrical Characteristics Absolute Maximum Ratings PARAMETER Voltages Referenced to GND SYMBOL VCC, TDP, TDM, CB, DP, DM, CEN Continuous Current into Any Terminal ※ Maximum junction temperature (plastic package) ※ Maximum storage temperature RATINGS UNIT -0.3 to 6.0 V ±30 mA Tj +150 °C TSTO -65 ~ +150 °C +260 °C ※ Maximum lead temperature (soldering 10s) Note: If ICs are stressed beyond the limits listed in the “absolute maximum ratings”, they may be permanently destroyed.
